Summary:

“No one said a thing when Rin left the cram school, they didn’t talk about what had occurred in the woods that night between the exorcist in training and the demon king of Earth, or what they had learned about their classmate because of it. They didn’t talk about how he was gone in the night before anyone could do a thing - or the fact that they probably wouldn’t have stopped him if they had known - or the brother that he had left behind - the twin that shared the same lineage as the son of Satan, not that the class talked of that either.

They certainly didn’t speak of how the only thing that Rin had left behind when he ran was the few things that he had brought with him to the dorms from the monastery and his tail, severed by the blade of a kitchen knife so that the Vatican couldn’t track the nephilim.

They didn’t speak of him at all, not until the night that he came back.”

Rin runs away from True Cross Academy after his lineage is exposed and he is released by the Vatican. He comes back more than a year later lined in bandages and with a red haired teen at his side, the pair asking for a favor.
